UW Map is a webapp that allows students to find their way around the University of Waterloo campus while avoiding all the traffic.

Deployment

Web Server

Deployment server is running Debian 12 (Bookworm).

$ pwd
~/uwmap

Set up DNS:

uwmap.live.             300     IN      A       {ip}
api.uwmap.live.         300     IN      CNAME   uwmap.live.

Get packages:

apt update -y && apt upgrade -y
apt install -y nginx python3 python3-pip nodejs npm certbot

Upgrade node, npm, and set up PM2:

npm install -g n
n latest
npm install -g npm@latest
npm install -g pm2
pm2 startup

Get dependencies:

python3 -m pip install -r backend_api/requirements.txt
npm install --prefix ./main-app

Get SSL certificates:

systemctl stop nginx
certbot certonly
systemctl start nginx

Set up reverse proxies:

cp {nginx-fastapi.conf,nginx-t3.conf} /etc/nginx/sites-available
ln -s /etc/nginx/sites-available/{nginx-fastapi.conf,nginx-t3.conf}  /etc/nginx/sites-enabled/
systemctl restart nginx

Generate secrets:

echo "- `openssl rand -hex 20`" | tee -a backend_api/keys.yaml

Run backend_api:

pushd backend_api 
pm2 start "TEST_ENV=0 uvicorn api:app" --name backend_api
popd

Run frontend:

pushd main-app 
npm run build
pm2 start npm --name "frontend" -- start
popd

Enable automatic startup after reboot:

pm2 save

ESP32s

ArduinoIDE is used to deploy firmware (./uwmap.ino) to the ESP32s.

To deploy, connect the ESP32 to the computer and set the partition scheme: Tools > Partition Scheme > Huge APP.

Modify the line containing the "url" string so that device_id=x refers to a desired ESP32 id.

If connected via usb, it is necessary to put the ESP32 into download mode by holding the Boot and Reset buttons simultaneously.

Select the correct board and port, then run Upload.

Developing

Documentation for the backend API is live at api./docs.
